1.In order to obtain more ideal results,the processing temperature can be increased,and the maximum temperature should not exceed 180℃ .
2.The most suitable extrusion temperature also depends on factors such as the compression ratio and length-diameter ratio of the user's extruder and the screw structure.

1.In order to obtain more ideal results,the processing temperature can be increased,and the maximum temperature should not exceed 180℃ to prevent the phenomenon of pre-crosslinking at high temperatures.
2.The most suitable extrusion temperature also depends on factors such as the compression ratio and length-diameter ratio of the user's extruder and the screw structure.
3.The radiation dose of the wire is based on the diameter of the wire,and the recommended radiation dose is 10 to 25 megabrads (Mrad).
